Preparation method of aerogel heat preservation felt and aerogel insulation felt
The invention discloses a preparation method of an aerogel heat preservation felt and the aerogel heat preservation felt. According to the technical scheme, the preparation method comprises the following preparation steps that a, aerogel particles are sprayed to the surface of a felt, negative pressure adsorption is conducted on the reverse side of the felt through negative pressure equipment, and the aerogel particles can enter the felt deeper; b, a phenolic resin solution is sprayed on the surface of the felt adsorbed with the aerogel particles by using a spraying device, and a negative pressure device is started at the same time to fix the aerogel particles inside and on the surface of the felt; and c, the felt in the step b is dried by using microwave equipment. The aerogel heat preservation felt comprises a layer of heat preservation felt with aerogel or a multi-layer composite heat preservation felt formed by bonding and connecting a plurality of layers of heat preservation felts with aerogel. According to the scheme provided by the invention, the production cost is low, the production period is short, powder falling is effectively prevented, and the heat preservation felt has the properties of heat insulation, fire prevention, noise reduction and hydrophobicity.
本发明公开了一种气凝胶保温毡的制备方法及气凝胶保温毡。本发明的技术方案是：包括以下制备步骤，a、对毡子表面喷洒气凝胶颗粒，利用负压设备，对毡子反面进行负压吸附，使气凝胶颗粒可以更深层次的进入到毡子里面；b、用喷洒设备对吸附有气凝胶颗粒的毡子表面喷洒酚醛树脂溶液，同时启动负压设备，将气凝胶颗粒固定在毡子内部以及表面；c、利用微波设备对步骤b的毡子进行干燥。气凝胶保温毡，包括一层带有气凝胶的保温毡或是若干层带有气凝胶的保温毡粘合连接形成的多层复合式保温毡。本发明提供的方案成产成本低，生产周期短，并且有效防止掉粉，保温毡具有隔热、防火、降噪且疏水的性能。
